In each project you are able to create and store multiple 3D pointer geometries. You can repeat some analyses with a pointer that represents a test probe, a thin stylus, or a gloved finger, all in the same project.

You can select the shape of the Pointer using the respective button; the Cylinder shape allows for the addition of a hemispherical tip if needed.

You can fill in the dimensions of your choice in mm and the Pointer will appear in the 3D visualization window, you can zoom and pad using your mouse wheel and right click-and-hold, respectively.

PRO TIP: The Pointer used for simulation does not need to be as long as an actual finger or test probe. The part close to the sensor is the major influence in Capacitance changes. So, using a Pointer of no more than 20 mm length should provide an excellent accuracy Vs time combination.

Your Pointer can be Dielectric or Conductive, simply select the respective material from the drop-down list at the bottom-right. You can add a new dielectric material in the library using the "Add New Material"=> "Dielectric" option at the top of the Stackup screen; all added materials are saved and can be used anywhere in your Project.

When you have selected a Covering, as in the example image above, materials for both the inner and the outer volume must be selected. Volume 1 is the inner one and only this is allowed to be Conductive.

Important: You must select a material from the drop-down list in every case, even when only one (conductive) volume is created.

The created Pointer is saved automatically, simply click back to "Pointers" tab to continue editing or to "Analysis" if you are ready to continue with setting up your Analysis.
